Product details

What this Li-ion protection IC covers and where it fits

The BQ24314DSGT is a single-chip battery protection IC for Lithium Ion packs, combining over-current, over-temperature, and over/under-voltage fault detection in one 8-WSON package.

Fault protection coverage and thermal envelope

The IC monitors four fault conditions: over-current, over-temperature, over-voltage, and under-voltage — a broader set than some single-function protectors that only catch over-current. The 8-WFDFN exposed pad (8-WSON 2x2) package requires a thermal land on the PCB to keep the junction within the 0°C to 125°C range during a sustained fault event.

Frequently asked questions

Is BQ24314DSGT obsolete?

No — the product status is Active per Texas Instruments. No PCN or EOL notice has been issued.

Can BQ24314DSGT be used for 2-cell Li-ion batteries?

The evidence lists the battery chemistry as Lithium Ion but does not specify the supported cell count. For a 2-series stack, verify the over-voltage threshold and the IC's absolute maximum input voltage against the pack voltage.
